I am currently trying to port a mod from 1.12.2 to 1.20.4, and I have found the guide on how to do so, but there doesn't seem to be a way to port directly from 1.12.2 to 1.20.4, and It seems tedious to go through and port one version to the next. I only need to port one file, not the entire mod, so I don't need to rewrite the structures of the entire mod from the ground up. The only thing that really needs to be changed are the imports, if there are functionally equivalent ones in 1.20.4. Is there any shorter guide, or a set of mappings I can use?
